This invention relates to machines for operating on shoes and is illustrated herein as embodied in a machine for use in pressing soles on shoe botoms.

A large volume of the shoes manufactured today are of the so-called compo or cement type in which the outsole is attached to the shoe bottom by cement alone. In cement attaching a sole to a shoe the sole must be positioned properly on the shoe bottom before pressure is applied to attach them permanently together. This sole position.- ing operation is sometimes performed by hand and sometimes by a cement sole attaching machine. T'he hand method is unsatisfactory because the position of the sole is dependent upon the judgment of the workman and it is not at all certain that every shoe operated upon Will have its outsole located in the proper position with respect to the shoe bottom.

With a cement sole attaching machine the p0- sitioning operation` is satisfactory but it often involves complicated mechanism on the pressing pad and, in multiple machines, a duplication of parts which may increase the expense of the machine considerably. Moreover, when the sole and shoe must be relatively positioned in the cement sole attaching machine before the sole attaching pressure can be applied, valuable time is consumed which might otherwise be used in applying pressure, thereby speeding up the machine and increasing its production.

An important object of the present invention is to overcome the above disadvantages by providing an improved machine for relatively positioning a sole and shoe and for securing them together in such position prior to the cement sole attaching operation.

To the attainment of this object the invention provides in its broader aspect improved means for positioning the sole relatively to the shoe which is accurate, rapid, and easy to operate., and it also provides improved means for pressing the sole and shoe together after they have been so positioned, these positioning and pressing means being adapted for operating on both right and left shoes irrespective of the shapes of the curves in their shank portions and the various mechanisms being so arranged and timed in their operation that they release the shoe as soon as it has been operated upon, thereby permitting shoes to be operated upon in rapid succession.

In accordance with one feature of the invention, the machine is provided with a sole and shoe receiving pad having a fixed portion for supporting the forepart of a shoe and a movable portion for applying pressure to the shank portion of the shoe. As illustrated, the movable portion is pivoted on the fixed portion and is swung toward the shoe by treadle operated 5 means to apply pressure to the shank portion of the shoe, this treadle operated means preferably producing only sucient pressure to conform the rear portion of the sole longitudinally to the shoe bottom and to stick the sole temporarily thereto. As illustrated, the treadle operated means is capable of swinging the movable portion of the pad a sufcient distance to permit it to operate on the shank portions of all types of shoes irrespective of their shapes.

In accordance with another feature of the invention, means is provided for supporting the rear portion of the shoe against pressure from the movable portion of the pad, said means being movable manually into operative position and returning by gravity to inoperative position as soon as pressure on the shoe is relieved, this shoe supporting means being locked against movement heightwise of the shoe when located in its operative position. As illustrated herein, the shoe 1 support locking means is operated automatically by movement of the movable portion of the pad toward the shoe bottoni, thereby insuring that the rear portion of the shoe will be supported before pressure is applied to the shank portion thereof. This locking means is also released automatically by return of the pad to its inoperative position.

Still another feature of the invention resides in the provision of improved positioning gages constructed and arranged'to engage the opposite edge faces of the heel portion of the sole and to position the sole relatively to the shoe bottom. As herein illustrated, the gages are actuated by spring means and are caused to position the sole relatively to the shoe by movement of the shoe supporting means into operative position. The gages are located in a predetermined position relatively to the movable portion cf the pad and are maintained in this position irrespective of the position into which said movable portion is swung in applying pressure to the shank portion of the shoe. Means is also provided for locking the gages upon contact with the sole, said means being likewise permitted to operate automatically 50 by movement of the shoe supporting means into operative position.

A still further feature of the invention consists in the provision of additional gages for relatively positioning the sole and shoe on the pad, 55

said gages being capable of adjustment to adapt them for operating successively on right and left shoes. As illustrated, the adjustable gages are arranged to operate at the ball line of the shoe and are so constructed that the gages which operate on one of these members, for example the shoe, may be shifted transversely of the pad as a unit relatively to the sole gages to vary the amounts that the shoe gages overhang the sole gages at opposite sides of the shoe and thereby to determine the proper extension which the sole f is to have relatively to the shoe bottom, this extension at the ball line usually being of a greater width at the outer side of the shoe than at the inner side so that, in right and left shoes, this greater extension is located at opposite sides of the pad. As illustrated, the mechanism for adjusting the gages consists of cams engaging means for actuating the ball line gages at both sides of the pad so that movement of the cams adjusts the shoe gages widthwise as a unit relatively to the sole gages without interfering with the actuating mechanism. Means is also provided ior varying the amount of widthwise adjustment of the shoe gages for operating upon shoes having sole extensions of different widths.

The above and other objects and features of the invention, including novel details of construction and arrangements of parts, will now be described in connection with the accompanying drawings and will thereafter be pointed out in the claims.

The machine is provided with a base 38 from which extend two upright walls 32, 34 (Figs. 1 and connected at their upper ends by a horizontal plate 36 to which is bolted a frame member 38 comprising a single upstanding wall located substantially centrally of the walls 32, 34. The frame 38 curves forwardly and has secured to its upper end, at an angle of substantially 45 to the horizontal, a transverse plate 4U of substantial width to which is secured by screws 42 (Fig. 2) a fixed. pad supporting table or plate 44 carrying a yieldable pad 46 preferably of solid rubber. The pad supporting plate is formed in two sections, a movable section 48 being pivotally connected to the forward end of the xed section 44 by pins 50 (Figs. l and 4) and being a1'- ranged to underlie the shank portions of a sole and shoe, the stationary section 44 underlying the foreparts of the sole and shoe. As shown in Fig. l, the movable portion of the pad supported by the pivoted section 48 of the support normally lies in the same plane as the xed portion of the pad supported by the section 44, but the section 48 may be swung upwardly above its pivots 50 to bring a sole and the movable shank portion of the pad into engagement with the shank portion of a shoe after the shoe has been clamped against heightwise movement relatively to the pad, as shown in Fig. 2.

The stationary section 44 of the pad support carries a plurality of sets of sole and shoe locating means including gages arranged to be moved simultaneously toward a sole placed on the pad by an operator, the gages being arranged to find the edge face of the sole and then to become locked so that the shoe gages on the several sets will be located in predetermined positions relatively to the edge face of the sole and will locate the shoe in the desired relation thereto. Two sets of sole and shoe gage mechanisms are located at acute angles to the longitudinal median line of the pad near its inner or toe end, as viewed rfrom the front, these sets being arranged to engage a sole and shoe in the vicinity of the tip line and being indicated generally in the drawings by the numerals 52, 53 (Fig. 4). The other two sets of `gage mechanisms, indicated generally in Fig. 4 by the numerals 58 and 58, are located near the outer end of the stationary support 44 and are arrangedto move inwardly substantially at right angles to the edge face of the sole in the vicinity of its ball line.

The four sets of positioning gages are actuated simultaneously by mechanism located at opposite sides of the frame 38 and connected, in a manner to be hereinafter described, to a treadle 58 (Fig. 1) pivoted on a shaft 60 located near description of the ball line gage mechanisms will be confined to the right-hand set 50 shown in Fig. 4, it being understood that the opposite set 58 is of substantially the same construction. The tip line gage mechanism 52 will then be described with reference to similar` or corresponding parts of the ball line gage mechanism 56, it being understood in this case also that the opposite tip line gage mechanism 54 is identical with the' set 52.

The xed pad support 44 is provided with four rectangular projections or blocks 60 (Figs. 6 and 7) two of which are located at the inner or toe end of the support and the other two of which are located substantially opposite the ball or break line of a shoe on the pad. These blocks 60 confine the forepart of the pad on the fixed support 44, the pad being held against sliding forwardly on the support by upstanding projections or blocks 62 formed on the pivoted section 48. The blocks 62 provide bearings for the pivot pins 50 and iit into recesses in the outer or shank portion of the pad, which portion is somewhat narrower than the forepart.

Secured to the upper side of the block 60 which supports the right-hand ball line gage mechanism is a transverse plate 64 (Figs. 7, 12 and 14) which overlaps the pad slightly and also extends outwardly of the support beyond the block 60. The plate 64 is provided with a central shouldered opening 06 (Fig. 14) and secured by screws to the upper surface of the plate are relatively thin plates 68, 10 the inner edges of which overlie the opening B6 and form a T-shaped slot. The plate 10 has an upwardly extending wall 12 at its inner edge having a fiat upper surface 14.

Mounted for sliding movement in the T-slot in the plate 64 is a slide member 16 the left-hand end 18 of which (Figs. 10 and 12) is reduced in width and extends downwardly toward the pad to form the sole gage member for finding the edge face of a sole placed on the pad. The other end of the slide 16 is pivotally connected by a pin (Figs. 10 and 1l) to the upper end of a substantially vertical lever 82 pivoted on a shaft 34 mounted in ears 36 extending outwardly from a block formed on the lower side of the padl support 44. The lever 82 extends downwardly below the pivot 84 and at its lower end is provided with a horizontal boss 88 (Figs. 11 and 13) to the forward side vof which, as viewed in Fig. 12, is pivotally secured by a pin 90 a casting 92. The casting 92 has a forward cylindrical portion extending at right angles to the boss 88 and surrounding a horizontal shaft 96, this portion forming a bearing for a bushing 94 which is rotatable in the casting and is connected to the shaft 96 by a key 98 (Figs. 11 and 12). The shaft 96, as best shown in Fig. 7, is supported for limited movement heightwise of the pad in a slot |00 formed in an arm |02 projecting downwardly from the forward end of the pad support 44, the shaft being held against sliding movement widthwise of the pad by collars |04 secured to the shaft and bearing against opposite sides of the arm |02.

At its outer or right-hand end, as viewed in Fig. 12, the bushing 94 is enlarged and has a cam |05 formed thereon thepurpose of which will be explained hereinafter. The upper portion of the lever 82 is provided with a laterally and'downwardly projecting arm |03, the outer end ||0 of which is bent at right angles to the arm, as shown in Figs. 10 and 11. Pivotal movement of the lever 82 around the shaft 84 will slide the sole gage 18 in the plate 64 toward and from the edge face of a sole on the pad.

The slide member or gage 1S, 10 has a U-shaped slot (Fig. 14) in its upper side in which is slidably mounted a member ||2 which, in turn, has a slot H4 formed therein. Adjustably-mounted in the slot H4 is a shoe gage H6 the inner or shoe engaging end of which is enlargedand projects upwardly,'as shown in Fig. 12. The shoe gage H5 is confined in the slot H4 by a cover plate |18 secured by screws |20 to the slide member |12, the screws passing through a slot |22 (Fig. 10) in the shoe gage lll to permit lengthwise adjustment of the latter relatively to the slide H2. The above arrangement permits the shoe gage to be adjusted laterally of the pad relatively to the sole gage 18.

The means for adjusting the shoe gage relatively to the sole gage is eccentric mechanism, indicated generally in Figs. 10 to 12, inclusiv-e, by the reference numeral |24, and substantially the same in construction and operation as the gage adjusting mechanism disclosed in Letters Patent of the United States No. 2,047,185, granted July 14, 1936, on an application filed in the names of Milton H. Ballard et al., this mechanism comprising, briefly, a frusto-conicall member rotatably mounted in the plate and having an eccentric pin |26 (Fig. 10) projecting downwardly into a transverse slot in the shoe gage I6 whereby, when the frusto-conical member is rotated,

the shoe gage is moved longitudinally relatively to the slide |12 and the sole gage 13. A handle |28 is provided for rotating the adjusting mechanism and a relatively heavy compression springl (not shown) maintains the mechanism in any position into which it may be adjusted.

The right-hand portion of the slide H2 is provided with an outwardly extending ear |30 (Fig. 10) whereby the slide is pivotally connected by a screw |32 to a lever |34 pivotally mounted on the shaft 84 and having a downwardly curved arm |96 the lower end of which is rounded and bears against the cam |06 previously referred to. The cam |09 is for the purpose of effecting an adjustment of the ball line shoe gage relatively to its sole gage to enable the ball line gage mechanism to operate successively on right and left shoes the sole extensions of which, at the ball line, are usually greater at the outer side of the shoe than at the inner side and which extensions, of course, in right and left shoes are located at opposite sides of the pad. Another cam |06 is provided at the opposite side of the pad for accomplishing the same adjustment on the lefthand ball line gages, as will be more fully explained hereinafter.

The arm is caused to bear against the cam 406 by the following arrangement. The hub of the lever E32, as shown .in 1l.. extends toward and engages the lever 84 thereby spacing these levers from each other lengthwise of the pad and providing a bearing for a relatively strong torsion spring i one end of which against the support 44 and the other end of which hooks around the lever 32, thereby tending constantly to swing this lever in a counterclockwise direction, as viewed in Fig. 12, to move the sole gage 18 inwardly toward the longitudinal median line of the pad. It will be seenA from the above that the lower arm of the lever 92, which carries the casting 92 and cam- |06, is thus urged constantly in a right-hand direction, as viewed in Fig. 12.

The lever 82 is provided with a second projection or lug |40 (best shown in Figs. l1 and 12) extending at right angles to the armv |08 and the lever` |34 is likewise provided with a lug |42 which is in alinement with the lug |40. Both lugs are provided with pins which support a compression spring |44 tending to urge the levers 82 and |34 in opposite directions, as viewed in Fig. 12, and thereby to keep them separated radially of the shaft 84 as much as is permitted by the associated mechanism. Consequently, the lever B2, when located in its inoperative position, as shown in Fig. 12 (which position is determined by other mechanism later to be described), is maintained in this inoperative position against the force of the torsion spring |38 which is tending to urge it in a counterclockwise direction into operative position. The compression spring |44 bears against the lug |40 which, in effect, is fixed relatively to the lug |42 and which, through the lug |42, forces the lever 34 in a clockwise direction to keep the two levers separated radially and also to hold the rounded end of the arm |36 against the cam |06.

Pivotally mounted on the shaft 84, rearwardly of the levers |34 and 82, as viewed in Fig. 12, is a third lever |46 which has pivotally connected to its upper end by a pin |48 a link |50 extending toward the pad and connected at its inner end by a screw |52 to the lower end of an arm |54 the upper end of which is in the form of a cylindrical boss |56 rotatably mounted on a shoulder screw |58 (Fig. 14). The screw |58 is threaded into an upstanding projection |60 on the rear portion of the slide T6 and the boss |56 is eccentric relatively to the screw so that when the arm |54 is swung in a clockwise direction, as viewed in Fig. 12, the eccentric portion of the boss will jam against the surface '|4 previously referred to, thereby locking the slide 16, and the sole gage 18 and shoe gage ||6 carried thereby, against movement away from a sole on the pad.

The lever |46 has a plate |62 secured thereto which extends outwardly and downwardly in line with the arm |08 on the sole gage lever 82. This plate has a cylindrical lower portion |64 surrounded by a compression spring |66 the outer end of which bears against the right-angle projection H0 on the arm |88. When the mechanism is in its inoperative position, as shown in Figs. and 12, the end of the cylindrical portion |64 of the plate engages the projection ||0 and the spring |66 is compressed, this spring being weaker than the torsion spring |38 or the compression spring |44.

The gage operating levers |34 and 82 and the lock operating lever |46 are normally held in their inoperative positions, by mechanism presently to be described, against the force of the torsion spring |38, thereby maintaining the sole and shoe gages in their open or retracted positions. When the mechanism holding these levers in inoperative position is released the torsion spring |38 forces the sole gage lever 82 in a counterclockwise direction, as viewed in Fig. 12, to move the sole gage |8 yieldingly toward the edge face of a sole on the pad. Since the lever |34 is connected positively to the sole gage lever 82 for movement toward the sole by the arm |36 bearing against the cam |06, the lever |34v moves inwardly toward the sole yieldingly with the lever 82, the spring |44 keeping the arm |36 against the cam and thus holding the two levers sepaoperative position.

rated. In other words, the levers 82 and |34 are maintained in the same relation to each other when they swing inwardly about the shaft 84 to move the gages toward a sole as when they are located. in their inoperative positions shown in Fig. 12, so that the sole and shoe gages remain in predetermined positions relatively to each other when they operate on a sole and shoe. Moreover, the compression spring |44 cannot yield to cause this position to change when a shoe is placed upon the sole on the pad because the shoe gage lever |34 is held positively against movement away from the sole by the cam |86. As stated above, the shaft 96 is arranged for limited movement heightwise of the pad in the arm |02 to allow for the swing of the lower arm of the lever 82.

As the levers 82 and 34 are swung inwardly as a unit about the shaft 84 to move the gages toward a sole on the pad, the lock controlling or operating lever |46 is also swung about this shaft in a counterclockwise direction, as viewed in Fig. 12, by reason of the positive engagement of the cylindrical end |64 of the plate |62 with the projection ||0 on the arm |68 of the sole gage lever 82. Accordingly, when the gage mechanism is permitted to operate the three levers swing initially as a unit about the shaft 84 under the yielding force of the torsion spring |36 until the sole gage IS nds the edge face of a sole on the pad.

During this movement of the gages toward the sole the link |50 on the lock operating lever |46 does not rotate the arm |54 about the screw |58 because the latter, being mounted on the slide portion 16 of the sole gage T8, has moved inwardly toward the sole with the rest 0f the mechanism. When, however, the sole gage contacts with the edge -face of the sole, the movement of the sole gage lever 32 and the shoe gage lever |34 stops. At this time the relatively light compression spring |66 between the arm |08 and the plate |62 expands and causes the lock operating lever |46 to continue its swinging movement in a counterclockwise direction, as viewed in Fig. 12, about the shaft 84. This movement causes the link |50 to rotate the eccentric |56 about the pin |58 until it jams against the surface 'I4 and thus locks the entire gage mechanism positively against outward movement away from the edge face of the sole. In other words, the sole and shoe gages 18, I6 are moved inwardly yieldingly toward the sole on the pad by the torsion spring |38 and, upon contact of the sole gage with the edge face of the sole, the locking mechanism is operated by the light spring |66 to lock the gages in their Reverse movement of the sole and shoe gage levers 82, |34 and the locking lever |46 unlocks the gages and returns them to their inoperative positions, this movement being accomplished by the gage actuating means reierred to above which acts directly on the gage locking lever |46, as will be hereinafter explained. Before describing how the gages are unlocked and retracted, the right-hand tip line sole and shoe positioning mechanism will be described and also the mechanism for operating both right-hand sets of gage mechanisms and for simultaneously operating the left-hand sets of gage mechanisms.

Referring to Figs. 2 and 4, it will be seen that the right-hand tip line sole and shoe positioning mechanism comprises a sole gage |68 and a shoe gage |70 carried, respectively, by slide members |12 and |`|4 mounted for longitudinal sliding movement in a plate |16 secured to a rear block 75 6o and provided with a T-siot ne, the soie and projecting ears |84 (Fig. 2) in which is mounted` a shaft |86. The tip line shoe gages do not have to be initially adjusted relatively to the sole gages to adapt them for operating successively on right and left shoes, because the extension of the outsole beyond the shoe upper in the vicinity of the tip line of either a right or a left shoe is substantially the same at both sides of the shoe. Accordingly, no mechanism for effecting such an adjustment is provided for the tip line gages. The sole and shoe gages E68, |16 are moved inwardly toward the sole by a torsion spring (not shown), similar to the spring |38, operating on a sole gage operating lever |88 (Fig. 4) pivoted on the shaft |86 and connected directly to the sole gage slide |14. When the gage actuating mechanism which normally holds the gages away from the sole is operated, the tip line sole and shoe gages move inwardly as a unit until the sole gage |68 finds the edge face of the sole, thereby positioning the shoe gage |16 for receiving the shoe and locating the shoe relatively to the sole. The lever |88 is provided with a downwardly extending arm |86 similar to the arm |68 having a right angle projection |92 thereon which engages the lower end of a plate |94 secured to a lock operating lever |96 and having a light compression spring |65 around its lower portion engaging the projection |62. The lever |66 is mounted on the shaft |86 and is connected at its upper end by a link |68 to eccentric locking mechanism, indicated generally in Fig. 4 by the numeral 208, and similar in construction to that on the ball line gage mechanism 56. The tip line gages are moved yieldingly as a unit toward the sole until the sole gage |68 nds the sole and then the lock operating lever |65 is swung forwardly by the spring |85, as described above, to operate the locking mechanism 266 and lock the tip line gages in operative position.

The ball line lock operating lever |46 and the tip line lever |96 are provided respectively at their lower ends with outwardly projecting arms 262 and 264 (Figs. 2 and 12). Pivotally connected to the arms 262, 264 are downwardly extending rods 286, 266 carrying lock nuts 2|6, 2|2 on their lower ends. These rods 266, 288 extend loosely through laterally extending arms 214, 2|6 on the upper end of an angle bar 2|8 (Figs. 2 and '1). The ball line and tip line gage mechanisms at the opposite or left-hand side of the pad are likewise connected by downwardly extending rods to similar laterally extending arms 220 and 222 (Figs. 4 and '7) on the upper end of another angle bar 224. These angle bars which, in plan View (Fig. 4), form a so-called spider arrangement, are secured to each other for movement heightwise of the pad at opposite sides of a thick portion 226 (Fig. '7) ofthe frame 68 through a slot 228 extending heightwise thereof.. The bars are secured together for heightwise movement in the slot 226 by spacing rolls 236 which have a sliding t in the slot and have reduced end portions upon which the angle bars are fastened by nuts 232. When the spider member is moved downwardly away from the pad the arms engage the lock nuts 2|6, 2|2 on the rods and swing the lock operating levers |46, |66, outwardly away from the pad. When, on the other hand, the spider member is moved upwardly relatively to the pay, thereby freeing the rods 286, 268, the torsion springs on the gage mechanisms move the sole and shoe gages on all of the mechanisms simultaneously toward the sole.

The angle bar 2|8 of the spider member has pivotally secured to it by a screw 234 a curved link 236 (Figs. l, 2 and '1) the lower end of which is pivotally secured by a pin 238 to the rear arm of a bell crank lever 246 pivoted on the frame 38 on a stud 242. A forward arm 244 of the bell crank lever 246 carries a pin 246 which extends through a slot 248 formed in the lower portion of a link 258 (Figs. 1 and 2) extending forwardly and downwardly and being pivotally secured at its upper end by a screw 252V to a forward arm 254 of a three-armed, yoked lever 256 straddling the frame 33 and pivoted thereon by a pin 252. The arm V244 of the bell crank lever has a tension spring 260 hooked to its upper end, the other end of the spring being secured to the lower end of the link 256. The pin 246 is normally held at the lower end of the slot 248 by the spring 26D, as shown in Fig. 1, the pin being permitted by the spring to move along the slot when the mechanism is operated.

The yoked lever 256 has a rearwardly extend` ing arm 262 to which is pivotally secured by a pin 264 an upwardly and forwardly inclined rod 266 pivotally secured at its upper end by a pin 268 to the rear end of shoe engaging member or presser foot 218. The presser foot 218 is pivot'ed between ears 212 on the frame 38 on a pin 214 and it has a forwardly extending arm 216 the end of which is curved downwardly and is provided with a toe rest or pad 286 adapted to engage and press the forepart of the shoe against the sole and pad. Counterclockwise movement of the lever 256, as viewed in Fig. 1, swings the forepart presser footl 216 about the pivot 214 to move the toe rest 288 into engagement with the shoe.

The lever 256 is provided with a third arm 282 extending forwardly at the left-hand side of the frame and pivotally connected by a pin 284 to a t'readle rod 286 which, at its lower end, is connected by a p-in 288 (Fig. 1) to the gage operating treadle 58.

The operation of the mechanism just described in elevating the spider member and permitting the torsion springs to move each set of gages inwardly to nd the edge face of the sole on the pad is as follows: Depression of the treadle 58 swings the yoked lever 256 in a counterclockwise direction, as viewed in Fig. 1, thereby swinging the presser foot 216 in the same direction about its pivot 214 to move the toe rest 286 toward the shoe. It is desired, however, that the gage mech anisms be operated to move the sole gages into contact with the edge face of the sole and to lock all the gages in operative position before the shoe is mounted on the sole and before the presser foot 210 has moved fully into operative position. Accordingly, movement of the lever 256, while moving the presser foot partly toward the pad, also moves the arm 254 and link 258 downwardly. During the first part of the movement of the link 256 the pin 246 is maintained by the spring 260 at the lower end of the slot 248 so that the bell crank lever 248 is rotated in a counterclockwise direction to elevate the curved link 236 and raise the four arms forming the spider member away from engagement with the lock nuts on the opposite pairs of rods 206, 208 connected to the lock operating levers of the gage mechanisms. Consequently, this initial depression of the treadle permits the four sets of gages to be moved simultan eously by their torsion springs toward the center of the pad until the sole gages find and contact yieldingly with the edge face of the sole, the gages thereupon being locked by continued movement of the lock operating levers |46, |96 in the manner already described.

Further depression of the treadle 58 stretches the spring 260 through continued lowering of the link 250 and permits the pin 246 to ride along the lslot 246 without further movement of the bell crank lever 240 but maintaining the spider member in its elevated position relatively to the lock nuts on the rods 206, 208. This further depression of the treadle also completes the operative movement of the presser foot 210 to bring thc latter int'o operative engagement with the forepart of a shoe which will, in the meantime, have been introduced on the pad by the operator in the position determined by the shoe gages.

In order that the operator may remove his foot from the treadle 58 after the gages have become locked so that he may introduce the shoe, and also so that he may thereafter depress another treadle with which the machine is provided for applying pressure to the shank portion of the shoe, means is provided for locking the treadle 58 in any position into which it is depressed. The elevated position of the treadle 58 is determined by a stop plate 29|) (Figs. 1 and 5) bolted to the lower portion of the wall 34 and provided with a rearwardly extending projection 29| arranged to engage the top of a pawl 292 pivotally secured by a screw 294 to the treadle 58. The pawl engages ratchet teeth 296 formed on a vertical edge of the stop plate 290 so that when the treadle is depressed the pawl will lock the treadle in any position into which it may be depressed. The pawl 292 is constantly urged into engagement with the ratchet teeth by a rod 298 pivotally secured at one end to t'he pawl and at its other end to the lower arm of a pawl release lever 300 pivoted on the treadle by a pin 302 and extending forwardly in position to be engaged by the operators foot. The rod 298 is normally urged forwardly by a spring 306 secured to a collar on the rod andfto the treadle 58. Stepping on the lever ll'forces the rod 298 rearwardly and swings the pawl away from the ratchet teeth thereby releasing the treadle 58. The treadle is normally maintained at the upper limit of its swinging movement by a heavy tension spring 308 (Fig. 5) extending between the treadle and a pin 3|0 in the frame.

When the treadle 58 is unlocked in the manner just described, the yoked lever 256 is swung in a clockwise direction, as viewed in Fig. l, to swing the forepart presser foot 210 into its inoperative position and to cause the spider member to pull downwardly upon the rods 206, 268, rst to unlock the gage mechanisms and then to withdraw the sole and shoe gages into their inoperative positions. The action of the several levers associated with each gage mechanism during this retracting movement is as follows: The lock operating levers |46, |96 of the ball and tip line gage mechanisms, for example at the rightlhand side of the pad, are swung outwardly or in a clockwise direction, as viewed in Figs. 4, 7 and 12, and the relatively light compression springs |66, |95 thereon are compressed until the plates |62, |94 contact with the projections H6, |92 on the sole gage levers 82 and |86. Thereupon the sole gage levers are swung positively in a clockwise direction about their supporting shafts against the torsion springs |38 which actuate the gage mechanisms. The cams |06 carried by the two ball line gage mechanisms are moved inwardly toward the pad as the upper ends of the sole gage levers swing outwardly. This permits the shoe gage levers |34 of these ball line gage mechanisms to be swung outwardly with the sole gage levers through the connection of the spacing springs |44 which, as stated above, constantly hold the lower arms |36 of the levers |34 in contact with the cams |06. Accordingly, the sole and shoe gages at both sides of the ball line will move simultaneously away from the sole and shoe into retracted position and the respective positions of the gage levers and the lock operating levers relatively to each other will be maintained except that the lock operating levers |46 will first move relatively to the other two levers of each set until the plates |62 contact with the projections I0. The movement of the tip line gages into retracted position is accomplished in substantially the same manner, the light springs |85 rst compressing to unlock the gages and thereafter the gage operating levers |88 operating positively to retract both the sole and the shoe gages from the tip line of the shoe.

As indicated above. the purpose of the cams |06 is to effect a simultaneous Widthwise adjustment of both shoe gages |6 at the ball line relatively to their sole gages I8 to adapt the ball line gage mechanisms for operating successively on right and left shoes, this adjustment being required because the amount of the sole extension beyond the upper at the outer side of a shoe is usually considerably greater than the extension at the inner side of the shoe at the ball line. It will be seen, therefore, that when operating successively on right and left shoes, the ball line shoe gages should be capable of adjustment preferably as a unit Widthwise of the pad relatively to the sole gages so that the amount that the shoe gage overhangs the sole gage at the side of the pad corresponding to the outer side of either a right or a left shoe is considerably greater than the amount of this overhang at the opposite side of the pad and so that this variation in the gages can be readily shifted from one set of ball line gages to the other.

In addition to adjusting the shoe gages simultaneously widthwise of the pad relatively to the sole gages to get a greater overhang of the shoe gage at the proper side of the pad for the shoe being operated upon, it is also desirable to vary this overhang of the shoe gage relatively to the sole gage for different types of shoes. For example, one type of shoe might have a sole extension at the outer side of the ball line which is one-quarter of an inch while the extension at the inner side might be seven thirty-seconds of an inch or less. This would, of course, be true of both the right and left shoes of that pair. On another type of shoe, however, the sole extension at the outer side of the ball line portion might be greater than indicated above and at the inner side it might be considerably less. Consequently, in addition to providing means for eiecting a quick and simultaneous adjustment of the shoe gages for right and left shoes, provision iS also made for varying the amount `and sole gages for different types of shoes.

of adjustment to accommodate shoes having different sole extensions.

The cams |06 operating on the arms |36 of the shoe gage levers |34 accomplish the simultaneous adjustment of the shoe gages for right and left shoes and they also determine the amount of widthwise variation between the shoe The left-hand cam |06, as viewed in Fig. '7, is carried by a casting 3|2 secured to the lower arm of the lever 82 and having a cylindrical portion surrounding the shaft 96 in the same manner as the right-hand cam |06 described above, the cam itself being formed on the end of a bushing rotatable in the casting 3|2 and keyed to the shaft 96. The casting 3|2 has a laterally extending portion 3|4 provided at its outer end with an upstanding lug 3 i6 also surrounding the shaft 96. Fastened by a screw 3|8 to the lug 3l6 is a circular plate 320 (Figs. 7 and 8) through which the shaft 96 passes and rotatably mounted on the shaft in front of the plate 320 is a U- shaped member having a relatively long inner arm 322 and a shorter outer arm 324 to which is secured a rod 326 having a hand nut 328 threaded on its upper end. Mounted on the rod below the hand nut 328 is a sliding block or collar 330 having an inner projection 332 extending into a slot 334 (Fig. 8) extending lengthwise of the long arm 322. A spring 336 on the rod 326 between the arm 324 and the collar 330 holds the collar against the nut 328.

Rotatably mounted on the shaft 96 at opposite sides of the shorter arm 324 are lower links 338, 346 of a lazy tong arrangement, theselinks having pivotally secured to their upper ends by pins 342, 344, another pair of links 346, 34B completing the lazy tongs. The upper links 346, 348 are pivotally connected by a screw 350 to the sliding collar 330. The shaft 96 extends laterally `beyond the outer link 340 and is provided on its outer end with a fixed collar 352 between which and the link 340 is a compression spring 354, this spring being strong enough to hold the mechanism by friction against the plate 320 in any position on the shaft intol which it may be swung. The plate 320 is provided at its right, as Viewed in Fig. 8, with a stop pin 356 which, as the parts are shown in that figure, is engaged by the lower link 338 of the lazy tong arrangement but which, when the mechanism is swung in a counterclockwise direction about the axis 96, as hereinafter described, is long enough to be also engaged by the lower link 340.

When it is desired to move the ball line shoe gages ||6 relatively to the sole gages 18 to shift the lar-ger overhang of the shoe gage relatively to the sole gage from one side of the pad to the other, for operating successively on right and left shoes having the same sole extensions on their outer sides but at opposite sides of the pad, the hand nut 328 is grasped and the entire assembly is swung in a counterclockwise direction relatively to the plate 320 and about the axis 96 from the position shown in Figs. l and 8 to a position in which the lower link 340 contacts with the stop pin 356, the compression spring 354 acting to hold the mechanism in this latter position against accidental rotation relatively to the plate 320. When the mechanism is swung about the axis 36, as just described, the lazy tongs and nut 328 will extend downwardly and slightly toward the right radially of the shaft 96, as viewed in Fig. 8. Since the arm 324 is keyed to the shaft 96, the shaft is rotated in its bearing |02 to turn the bushings in the castings 92 and 3|2, which are likewise keyed to the shaft, thereby rotating the cams |06 a distance such that the cam surfaces thereon will shift the greater overhang of one shoe gage 6, for example, the righthand shoe gage in Fig. '7, over to the left-hand shoe gage and simultaneously to shift the righthand shoe gage into the retracted position originally occupied by the left-hand shoe gage. In this way a quick adjustment is obtained for operating successively on right and left shoes.

When it is desired to vary the amount of the overhang of the shoe gages relatively to the sole gages, the hand nut 328 is turned on the threaded stem 326 to raise or lower the nut and thereby to open or close the lazy tongs and thus to change the initial position of the stem 326 and the rest of the assembly radially of the axis 96 and relatively to the pin 356 in the plate 320. Adjusting the nut 328 heightwise of the stem 326, of course, turns the shaft 96 and the cams |06 into a different initial position so that the relative positions of the sole and shoe gages laterally of the pad are likewise chan-ged. Moreover, when the stem and lazy tong mechanism is` swung in a counterclockwise direction about the axis 96 to effect the adjustment, as described above, the stopping position of the link 340 against the stop pin 356 will be such that the shoe gages will be shifted amounts determined by the adjusted positions of the lazy tongs.

During the positioning of the foreparts of the sole and shoe and the clamping of these portions j against the forepart of the pad 46, the movable section 48 of the pad support is located in the same plane as the fixed section 44, that is, at an angle of substantially 45 to the horizontal, as shown in Fig. 1. The shank and heel portions of the sole, therefore, except in the case of a conformed or premolded sole, will lie flat against the shank portion of the pad with the heel portion of the sole projecting forwardly beyond the end of the pad. Means is provided for finding and gripping the projecting heel portion of the sole and for positioning it widthwise with respect to the heel portion of the shoe while the sole is still flat on the pad with its shank and heel portions spaced from corresponding portions of the shoe bottom. After the shank and heel portions of the sole and shoe have been properly alined with each other, the movable section 48 of the pad support is swung upwardly toward the shoe to press the sole into engagement therewith. Before this occurs, however, mechanism associated with the heel positioning mechanism is operated to engage the last in the shoe and to support the rear portion of the shoe against pressure from the shank portion of the pad, this mechanism being locked against movement heightwise of the shoe when located in operative position.

The mechanism for relatively positioning the -shank and heel portions of the sole and shoe is best illustrated in Figs. 1, 2 and 15 to 21, inclusive. The frame 38 is provided at its forward edge some distance below the pad with a boss 358 (Figs. 1 and 2) in which is secured substantially at right angles to the plane of the pad and approximately under the ball line of a shoe mounted thereon an upwardly projecting stud 365|. Rotatably mounted on this stud is a casting 362 having upwardly projecting ears 363 which support a horizontal shaft 364 extending widthwise of the machine. Fulcrumed on the shaft 364 near its central portion is a lever 366 which extends forwardly and has an upwardly projecting arm 368 the upper end of which is wide and at and engages a rounded projection 310 on the under side of the movable section 48 of the pad support. The lever 366 normally supports the section 48 in the position shown in Fig. 1 and is arranged, in a manner to be hereinafter described, to swing this section upwardly toward the shoe to bring the sole into engagement therewith and to conform the sole and pad to the shape of the shoe bottom. A tension spring 312 connected to a lower portion of the lever and to a pin in the rounded projection 31|) maintains the projection in engagement with the arm 368 while permitting the projection to slide along the at surface thereon during swinging movement of the section 48.

The lever 366 has a lower arm 314 which has pivoted thereto on a pin 315 a forwardly and upwardly extending arm 318 of considerable width, as shown in Fig. 5, and having an upper portion 380 which supports the mechanism for engaging the heel portion oi the sole and positioning it and the shank portion of the sole relatively to the shoe bottom. This heel positioning or gage mechanism is located in a predetermined position heightwise relatively to the movable section 48 of the pad support and, since it is pivotally connected to the lever 366 which supports this movable section, always remains in this predetermined position, although it may, if desired, be adjusted heightwise relatively to the support 48 to accommodate different types of soles, for example, conformed or premolded soles. Before eX- plaining how the heel gage mechanism acts to position the heel and shank portions of the sole relatively to the shoe bottom, which operation takes place in conjunction with the movement into its operative position of the means referred to for supporting the heel portion of the shoe against pressure from the pad, the construction of the gage mechanism itself and its operation in engaging and gripping the heel end of the sole will be explained.

Referring to Figs. 15 to 21, inclusive, the upper end 388 of the gage supporting lever 318 is provided with a transverse slot 382 (Figs. 17 and 18) in which are slidably mounted heel gages 384, 386. The gage 384 comprises a slide portion 388 mounted in the slot 382 and having an upwardly projectingr portion 385 the upper end of which forms the gage proper, the latter comprising a lower ledge or lip 382 (Fig. 16) of considerable length projecting inwardly over the pad, and an upper and shorter inwardly projecting lip 384 arranged to overlie the sole when a sole edge engaging surface 396 on the gage nds the edge face of the sole. The opposite gage 385 has a slide portion 358 and an upwardly projecting portion similar to the gage 384 formed on the end of the slide portion and carrying at its upper end a gage member provided with lower and upper lips 392, 384 and a sole engaging surface 396 of the same construction as the opposite gage. When the sole is lying hat on the pad the heel gages 384, 386 are in such a position relatively thereto that the projecting `neel portion of the sole rests on the lower lips 362 of the gages, as indicated in broken lines in Fig. 16.

The slide portions of the heel gages are conned in the slot 382 by a cover plate 402 (illustrated in detail in Fig. 19) which is cut away at kthe proper places to permit widthwise sliding movement of the gages. The gages 384, 386 have projecting downwardly respectively from their lower sides pins`404, 486 between which extends a relatively heavy tension spring 408, the spring passing through a hole 4i0 in the upper portion 338 of the arm 318. The spring 488 tends normally to urge the gages toward each other to bring their sole contacting surfaces into engagement with the opposite edge faces of the sole supported by the lower lips 392.

Mounted in the central portion of the cover plate 482 is an upstanding shoulder screw 4I2 upon which is rotatably mounted a lever 414, hereinafter referred to as the heel gage actuating lever. The lever 4l4 has pivotally secured to it at opposite sides of the center 4I2 a pair of curved links 4I6 and 4|8, best shown in Fig. 15, these links being secured respectively to the lever by screws 420, 422. The opposite end of the link 4I6 is secured by a pin 424 to the slide portion 388 of the right-hand sole gage 384 and the link 4i 8 is secured by a pin 426 to the slide portion of the left-hand gage 386. Pivotal movement of the gage actuating lever 414 in a clockwise direction, as viewed in Fig. 15, will separate the gages into their open or retracted position and reverse movement of the lever will permit them to close yieldingly upon a sole through the action of the spring 488, as will be explained more fully hereinafter. The lever 4|4 has an upwardly projecting lug or ear 428 at its forward end in the upper portion of which is threaded a screw 438 (Fig. 15) which projects forwardly beyond the lug.

Rotatably mounted on the shoulder screw 4|2, above the lever 414, is another lever 432, hereinafter referred to as the gage locking lever, having a forwardly extending arm (Fig. 15) the outer portion of which is in the form of an upstanding block 434. When the gages are retracted, as shown in Figs. 15 to 18, inclusive, the projecting portion of the screw 438 engages the adjacent side of the block 434 and acts as a stop to determine the positions of the two levers relatively to each other about the pivot 4|2. A relatively light compression spring 436 surrounds the screw 43|] between the ear 428 and the block 434, as best shown in Fig. 15, and, when the mechanism is positioned as illustrated in that figure the spring is under a light compression.

The lever 432 has a rearwardly extending arm to which is pivotally secured by a screw 431 a link 438 secured at its opposite end by a screw 440 to a laterally extending arm 442 of a locking member 444 rotatably mounted on a pin 446 and having an eccentric portion 448 (Fig. 15) arranged, when the locking lever 432 is swung in a counterclockwise direction, to engage a finished surface on an upstanding projection 450 formed y on the rear portion of the cover plate 402. When the eccentric 448 engages the projection 458 it jams and prevents the spring 488 from moving the gages further inwardly toward the sole, thereby locking the gages in operative position.

The block 434 on the gage locking lever 432 is connected by a universal joint arrangement 452, including a spring 453, to the upper end of an arm 454 of a bell crank lever pivotally mounted at its lower end on a pin 456 (best shown in Figs. 1, 2 and 15) carried by a boss in the lower portion of the gage supporting arm 318. The bell crank lever has a lower laterally extending arm 458 which carries on its outer end a roll 468. The arm 454 of the bell crank lever is normally maintained in an upstanding position, as shown in Figs. 2, 5 and 15, to hold the gage mechanism in an open or retracted position against the tension of the spring 408 by contact of the roll 468 with a lug 462 (Figs. 1 and 2) mounted on further mechanism, presently to be described, the lug bearing against the roll and expanding the spring 408. When the weight of the mechanism referred to is removed from the roll 461), the spring 408 moves the heel gages yieldingly into engagement with the opposite edge faces of the heel portion of the sole. When the gages meet the opposite edge faces of the sole the light spring 436 between the gage actuating lever 414 and the lock operating lever 432 expands to force the lock operating lever further in a counterclockwise direction, as` viewed in Fig. 15, to operate the lock 448 and thereby to lock the gages against further movement toward the sole. Downward pressure on the roll 4611 moves the arm 454 toward the left, as viewed in Fig. 15, rst to bring the block 434 against the end of the screw 436 and thereby unlock the gages, and thereafter to move the levers 414, 432 as a unit in a clockwise direction against the force of the spring 408 to open the gages to their retracted positions.

The mechanism for causing the heel gages to operate in a manner just explained and for causing shank and heel portions of the sole to be properly positioned widthwise relatively to the shoe bottom, and also for supporting the heel portion of the shoe against upward pressure from the movable portion of the pad will now be explained.

Pivotally mounted on the transverse shaft 364 (Figs. l and 2), at opposite sides of the pad elevating lever 366, is a pair of forwardly and downwardly extending arms 464 (Figs. 1, 2 and 5) having pivotally mounted near their forward ends on pins 466 a pair of substantially triangular plates 468, each provided at its upper portion with a projection or arm 416. Pivotally mounted on studs 412 in the ends of the arms 411] is a combined shoe engaging and last supporting member 414 which, as shown in Figs. l, 2, 5 and 6, has a substantially V-shaped shoe engaging portion 416,v

a projection or lip 418 overhanging they V-shaped portion, and a downwardly curved arm 486 which provides a handle for grasping the positioning member and moving it into a position to nd and o embrace the heel portion of the shoe and also to engage and rest upon the heel portion of the last in the shoe. The inner sides of the two triangular plates 468 are finished surfaces and have a sliding t with finished surfaces 462 (Figs. l and vmanually into operative position. Since it can be swung laterally of the shoe about the center 360 (Figs.` 1 and 2'), and can swing heightwise during such lateral movement about the centers 364 and `316, it will be seen that the comb-ined shoe gage and last support 414 can be readily moved into any position necessary to contact the heel end of the last and shoe. Moreover, since the heel sole gage mechanism is mounted on the arm 3-18 which, in turn, is pivoted to the lever 366, which is also arranged for lateral swinging movement about the center 360, any widthwise movement of the member 414 will impart a corresponding lateral movement of the mechanism which supports the heel sole gages, although this latter mechanism at that time will not be moved height- Wise of the pad as will the shoe gage and last support through manual operation by the operator.

As stated above, after the operator moves the shoe engaging member or gage and last support 414 into operative position, as shown in Fig. 2, thereby positioning the heel end sole gage mechanism (which is then gripping the sole) laterally with respect to the rear portion of the shoe, the last support becomes locked against heightwise movement so that the shoe will be supported against pressure from the shank portion of the pad. The locking of the last support takes place automatically during the operation of the mechanism for moving the shank portion of the pad against the shoe bottom.

In order to move the movable section 48 and the pad toward the shoe bottom the lever 366 is swung upwardly about the pivot 364 by a treadle, the lever 366, of course, and the sole gages having been rst swung laterally about the center 366 with the last and shoe engaging member 414 as previously explained. Pivotaly connected to the lever 366 by the pin 316 is a downwardly extending bar 484, which may be conveniently termed the pad elevating bar and which, at its lower end, is pivotally connected to a bell crank lever 486 by a pin 4687 the pin being loose in the bar (as shown in Fig. 2) to permit the latter to swing laterally of the pad withthe lever 366 without affecting the bell crank lever 486. The bell crank 486 is pivotally secured in the frame 38 on a pin 496 and has an upwardly extending arm 492 carrying a pin 494 which extends through a slot 466 formed in a downwardly extending link 498 provided at its lower end with another slot 499 through which passes a pin 561| mounted in the frarne 32 (Figs. 2 and 3). The bell crank lever 486 has a rearwardly projecting arm 562 which is pivotally connected by a pin 564 to a treadle rod 566 which, in turn, is pivotally secured at its lower end (Fig. l) by a pin 563 to a treadle 5111 pivoted on the shaft 66 and normally held in an elevated position by a heavy spring 51 1 (Figs. 1 and 5). Depression of the treadle 516 swings the bell crank lever 466 in a clockwise direction, as viewed in Fig. 1, to move the bar 484 upwardly and thereby to cause the pad supporting lever 366 and the gage supporting lever 316 to move the pad and gages upwardly and thus bring the sole supported therebi7 against the bottom of the shoe, as shown in Fig. 2.

The arms 464 on the transverse shaft 364 have forwardly extending portions 512 connected together by a transverse pin 514. Loosely mounted on this pin by an enlarged hole (Fig. 2) is a downwardly and rearwardly extending bar 516 which extends through a casting 518 pivotally mounted between the frame members 32, 34 by the pin 566 andvby a second pin 5211 (Fig. 3), these pins being secured in the frame by set screws 522. The lower portion of the bar 516 has ratchet teeth 524 formed thereon, as shown in Figs. l and 2, and is reduced in size to form a shoulder 526 about midway of its length. When the shoe gage and last support 414 and the mechanism associated therewith are located in an inoperative position, as shown in Fig. 1, the shoulder 526 rests against the top of the casting 518 thereby determining the inoperative position of the arms 464. Since the triangular plates 468 are pivoted at 466 on these arms 464 they will normally drop forwardly and downwardly away from the pad. The limit of their downward swinging m-Ovement about the pins 466 is determined by adjustable stop screws 528 in lugs on the arms 464 and arranged to engage lugs 530 formed on the lower ends of the triangular plates y468.

The casting 5|8 has rearwardly projecting ears 534 between which is pivotally mounted on a pin 536 a pawl 538 having an upwardly projectingtail 546 (Fig. 2) engaged by a roll 542 mounted on the link 498. The position of the link 498 normally holds the roll 542 against the tail 546 of the pawl 538 and thereby keeps the pawl out of engagement with the ratchet teeth on the bar 5|6 against the action of a spring 544, connected at one end to the pawl and at its other end to the casting 5I8. Release of the pawl permits it to engage the teeth 524 and thereby to lock the bar 516 and all the mechanism supported thereby in any position into which the mechanism may have been moved while the pawl was held inoperative. The roll 542 is normally held positively against the. pawl 538 by the bell crank lever 486 forcing the pin 494 against the lower end of the slot 496 in the link 498, as shown in Fig. l, the bell crank lever, of course, being maintained in its inoperative position by the elevated treadle and its spring 5I I. Consequently, when the treadle 5|l is depressed to rotate the arm 462 in a clockwise direction, as viewed in Figs. l and 2, the slotted link 488 is' moved upwardly by the tail of the pawl 538 under the action of the spring 544 in pulling the pawl into engagement with the teeth 524. The slot 496 is long enough l so that after the locking mechanism has operated, as shown in Fig. 2, the pin 454 still has clearance in the upper slot 496 to permit continued rotation of the bell crank lever 486 in elevating the pad and gage mechanism for a shoe having a relatively steep arch.

As indicated above, the sole gage mechanism may be adjusted heightwise of the supporting lever Y318 to adapt it for operating on shoes having extremely high arches or, if desired, for operating on soles which have been preconformed to the shape of a last. This adjustment is readily accomplished by making the top portion 388 of the gage supporting lever separate from the lower portion 38 and securing these two members together by any usual means such, for example, as' a screw 546 (Figs. .1 and 2)', the contacting surfaces of the two portions of the lever being preferably corrugated horizontally so that they will interlock in adjusted position.

K In order to maintain the gage supporting lever 318 in an upwardly extending position, that is, to prevent it from swinging forwardly about its pivot 316 the following mechanism is provided. An arm 548 is pivoted on the pin 316 and extends upwardly behind the gage supporting lever 318, as viewed in Figs. l and 2. 'I'he upper end of the arm 548 has a finished surface 556 (Fig. 2) which is arranged to bear and ride on the front end of the pad supporting section 48. The arm 548 is held inwardly to keep the surface 550 against 'the section 48 by a tension spring 552 secured at one end to the arm and at its other end to a pin 554 mounted in` the pad supporting lever 366. About midway of its length the arm 548 is provided with a laterally projecting pin 556 through which is threaded a forwardly extending rod 558, the forward portion of the rod passing loosely through another pin 56|] on the gage supporting lever 318. The rod 558 has a shoulder 56I thereon against which the pin 56B is caused to bear by a compression spring 562 extending between the two pins 556, 588 and holding the arm 548 and lever 318 separated from each other. The forward end of the rodV 558 is provided with a hand wheel 564 whereby the rod may be adjusted forwardly and rearwardly relatively to the arm 548 to move the gage supporting lever 318 and the heel gages toward and away from the movable section 48 of the pad support. In this way the gages may be moved as a unit lengthwise of the shoe until they are positioned to engage the projecting heel portion of the sole at the desired location lengthwise, this position preferably being near the widest part of the heel end of the sole. The spring 552, of course, yields to allow for the swing of the section 48 as it is moved toward and away from the shoe bottom.

In the operation of the machine the operator places a sole A on the pad 46 while the latter is flat, as shown in Fig. l, the projecting heel portion of the sole resting loosely on the heel gages 384, 386. He then depresses the treadle 58 to move the forepart sole and shoe gages inwardly toward each other until the sole gages find the opposite edge faces of the sole and become locked in such position. During this operation the forepart holddown or presser foot 210 has been moving toward the pad. After the forepart gages have become locked the operator removes his foot from the treadle which, through the lock 290, 232 (Fig. l) remains in this depressed position, and he places a shoe B on a last L on the forepart' of the sole in the position determined by the locked shoe gages, as shown in Fig. 2. The operator then completes the depression of the treadle 58 to bring the presser foot 218 into engagement with the forepart of the shoe and press it and the sole firmly against the xed portion 44 of the pad, the presser foot remaining in such position because the treadle becomes locked again when the operator completes its depression. The operator next grasps the handle 480 of the heel gage and last supporting mechanism and swings the heel gage 416 upwardly and as much laterally as is necessary to cause it to embrace the heel end of the shoe and to cause the support 418 to rest on the heel end of the last. In doing this the operator has moved the heel sole gage mechanism laterally with the shoe gage by reason of the triangular plates 588 contacting with the gage supporting lever 318 and the mechanism associated therewith. Consequently, the sole and shoe are now positioned laterally throughout their entire areas, the shank and heel portions of the sole, if necessary, having been moved relatively to the forepart by the foregoing action while the sole was still resting flat on the pad so that it was spaced from the shoe bottom during the positioning operation.

The operator depresses the pad elevating treadle 5H) which rst frees the locking paw] 538 (Fig. 2) and causes it to' lock the bar 5|6 against further upward movement, thereby locking the last support 413 in operative position. Immediately thereafter the pad elevating bar 484 and lever 366 swing upwardly about the pivot 364 to swing the pad supporting section 48 and the movable portion of the pad 46 about the center 50 and thereby to bring said portion and the shank portion of the sole A forcibly against the shoe bottom and apply pressure to the shank portion of the shoe bottom. The operator may then release the treadle 5H! which permits the movable portion of the pad and its supporting mechanism to swing downwardly away from the shoe and in so doing tol release the locking pawl 538 so that the bar 5 I6 is free to descend after the last support and shoe gage 414 have swung outwardly away from the last and shoe, this action occurring almost instantly. As the last support and shoe gage swing outwardly and downwardly into inoperative position about the pivot 466, the lug 462 (Figs. 1 and 2) engages the roll 460 on the bell crank lever 454 and thereby operates the sole gage locking and actuating levers (Figs. l5 to 18, inclusive) to withdraw the heel gages from the edge face of the sole positively against the spring 408. The heel ends of the sole and shoe are now entirely free from the last support and the shoe and sole heel gagesand the shank portion of the shoe is free from the pressure of the movable shank portion of the pad which has now returned to its normal position in the same plane as the xed portion. The operator next actuates the treadle release 300 to permit the locked treadle 58 to return to its elevated position and, through the various connections previously described, to unlock and withdraw the forepart sole and shoe gages and return the presser foot 210 to its inoperative position, thereby permitting removal of the shoe with the sole properly positioned and temporarily attached or spotted on the shoe bottom.

The mechanisms of the machine are so constructed and arranged that the entire operation of spotting the sole on the shoe bottom may be performed quite rapidly since the timing is such that the various functions of the several mechanisms occur in very close sequence. Accordingly, the operator may present to the machine soles and shoes which have been previously treated with cement at their marginal portions for permanently attaching the sole to the shoe bottom such, for example, as pyroxylin cement, and have preferably, but not necessarily, been spotted at their central portions with an initially tacky or quick setting cement, and he may operate on these shoes in rapid succession. The only adjustment he will have to make for a quantity or lot of shoes ranging from large to small sizes will be the adjustment provided for varying the positions of the ball line shoe gages relatively to their sole gages for operating successively o-n right and left shoes. Since this adjustment is quickly made by swinging the lazy tong mechanism from one position to another by the nut or handle 328, practically no time is lost in operating successively on right and left shoes. When the sole extension of a pair of shoes varies from those previously operated upon, or when the arc in the shank portion of a shoe is extremely high or low so that it is outside the range that the machine has been set to accommodate, the other adjustments referred to may be made'.

After the shoes have had their outsoles properly positioned and spotted by the present machine they may be placed immediately in a sole attaching press of any usual or conventional type and have the outsoles permanently attached by holding the shoes under relatively heavy pressure while the sole attaching cement is setting. If desired, the shoes may be stacked in a rack after the soles have been spotted by the present machine and, when the rack is full, it may be moved to a multiple station cement sole attachingmachine in which the solesmay be permanently attached. This is possible because the speed with which the present machine can be operated is such that a comparatively large number `of shoes can have their soles spotted before the slower setting sole attaching cement can set sufliciently to` interfere with the sole attaching operation.
